(3) LED print head
The LED print head is comprised of an LED array, SELFOC lens array, and an LED print head memory PWB. The LED
array arrays 5120 of LED chips in line. It also includes the driver circuit for the LED array. The light which is switched on
and off depending on video data irradiate the drum through the SELFOC lens, to form an image. The LED head is of 600
dpi, therefore the exposure of the light is as dense as 600 dots per a inch. The LED print head memory PWB stores data
for compensation of fluctuation of luminosity over all LED chips in the array.
